Hi, I have a really strange server problem that I've never experienced before. The setup is a debian lenny server with latest updates, ispconfig2 and ossec installed, a hardware raid (3ware) - nothing else installed that I would call "special". After a (i believe) random amount of time the network of this server completely(!) stops working. That means I cannot even ping localhost or 127.0.0.1 There is nothing special in any log. /var/log/syslog, /var/log/messages, apache log, postfix log, proftp log, /var/log/kern, /var/log/dmesg - everything normal despite the fact that suddenly everything network-related stops working. I can still do anything via serial remote console, top shows no process running (all sleeping) - load is at zero. Memory consumption normal. I have no further idea what to do. As this is a hosting server with customers on it i can not simply re-setup the server - but I already did this before. The complete server hardware has already been exchanged (only raid controller and disk drives have been held). Some customers have "baseportal" installed - I do not appreciate that but I cannot believe that this could cause those problems - should be in the logs then. Could anyone maybe point me to the right direction? Thank you.
